We got my wife's new Macbook Pro. Did a fresh backup in SuperDuper to a partitioned external HD, plugged it into the new laptop, selected that partition as the source for transferring stuff, and am getting an error message that the partition is a case sensitive file system while the new laptop is case insensitive.

So, now what do I do? Is there some way to create a new backup on the external hard drive that is case insensitive? Never seen this before. I upgraded her to High Sierra on the original machine a week ago hoping to avoid any compatibility issues with the file systems and now this.
